A pair of Apple patent filings discovered by AppleInsider this week show the company is exploring ways to leverage the iPhone's wireless technologies to alert users when they are about to lose a WiFi or cellular signal, and also help them find tiny accessories that may have been misplaced.
The first filing describes methods of providing iPhone or iPod touch users with an "out of range" warning that includes an estimate of the amount of time remaining until the devices are out of range of a WiFi network, thus presenting the users with an opportunity to take corrective measures if they so desire.
